Hello, It looks like you have either our S351, with a 15-002 bottom attachment, or S390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You would also need a 2740 spring strength option for the 28" balances shown in your photos. You also mentioned that you had 17 4 stamp balances, which would require 1740 strength options for 18" balances. Thank you! 
Comparison of the S351 and S390 balance shoes.
